August 3, 1934
At the age of forty-nine, Pyotr Yermakov, employed since 1927 as inspector of prisons for the Urals, was drawing his pension. Always anxious to boost his role not just in the Romanovs’ murders but in the Revolution itself, he continually toured schools and Young Pioneer camps around Sverdlovsk, as Yekaterinburg was now renamed, lecturing children about his “heroic” deed.
General Yevgeny Miller, chairman of ROVS, was asked to approve the execution of Yermakov. Once the execution was approved, Intelligence Service agents began planning the act.
Yermakov was located in Sverdlovsk. The operation involved professional lookouts, in a nearby apartment rented much earlier, and a minute study of Yermakov’s daily routine. The Intelligence Service’s agents, led by Rodion, planted another of his bombs under the driver’s seat of Yermakov’s red Ford Model A, filled with just enough explosive to kill all the passengers while avoiding harming others.
On August 3, 1934, Yermakov called home to tell his wife to expect guests for Sunday luncheon. He had met up with two comrades, Nikolai Pospelov and Aleksandr Bozhenov, both of whom had been present at the Romanovs’ burial, and invited them home for a meal. As they got into their car, “Rex,” chief of the Intelligence Service division responsible for assassinations, and Rodion were sitting in another car, watching them, after many tense hours of surveillance, during which the local militsiya almost caught the Whites.
Yermakov’s wife was standing on her balcony watching as her husband steered the car up a concrete ramp in front of their apartment building. As the car reached a retaining wall on one side of the driveway and an open field on the other, the mercury in the tilt fuse under Yermakov’s seat finished flowing to the top of the tube and closed the circuit, which had been activated by a timing device. In a plume of black smoke, the car's roof disintegrated and the doors burst open. By the time the ambulance arrived 45 minutes later, Yermakov and his two companions were dead. His buttocks and part of his back had been blown away by the powerful bomb, which had set the car ablaze.
